Prysmian will design, manufacture and install submarine and land-based cables for “Lot B” comprising seven projects totaling over 900 kilometers of high-voltage alternating current (HVAC) cables, with final delivery expected in 2033. Reaching water depths of up to 1,150 meters, the Italian company said it would set a new record depth for static three-core HVAC cables. The signing of the agreement is subject to customary statutory conditions and regulatory clearances, and its execution is conditional upon the issuance of a notice to proceed by the customer. “This is a step-forward for Greece. We know from our prior experience in the country just how essential and welcomed upgraded electrical infrastructure is for residents in island communities,” said Raul Gil , EVP Transmission at Prysmian. “We will utilise our assets – from design, manufacturing, surveying and installation, including our flagship deep-water vessels – to deliver these vital upgrades, and we are excited to see the positive impact of our hard work for the thousands of residents and visitors to these islands in the very-near future.” Prysmian previously worked with IPTO to deliver several projects, including the Cyclades Islands interconnections (Evia, Andros and Tinos, and Syros-Lavrio), the Crete-Attica and the Crete-Peloponnese, where the company set the previous record depth in the HVAC field, installing cables at approximately 960 meters under the sea.
